PUMP.

SPECIFICATION forming part of Letters Patent No. 419,197, dated January14, 1890- Application filed August 19, 1889. Serial No. 321.324. (Nomodel.)

To @ZZ whom it may concern.-

'Be it known that I, NICHOLAS S. HILL, a citizen of the United States,residing at Shilllngton, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inPumps; and I do declare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the sam'e, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification. v

This invention relates to pumps adapted more particularly for cisterns,dac.

The objectis to furnish a pump which can be readily put in position,adjusted to different depths of wells, and kept in repair without theassistance of a skilled mechanic or the necessity for tools which arenot constantly at hand.

The invention consists, mainly, in a construction which permits the pumpto be quickly and easily changed from single to` double acting, andwhich permits the lengthl of the piston-rod and casing to be easilyichanged to adapt the pump to any desired location.

The features are fully set forth herein and specifically pointed out inthe claims.

Figure l is a sectional View of a pump embodyin g myinvent-ion. Fig. 2is a plan of the lower piston-shell. Fig. 3 is a plan of t-he lowerpiston perforated disk. Fig. 4 shows the strip of leather from which thelower piston-bucket is formed. Fig. 5 is a plan of the suction-valve inlower cylinder. Fig. 6 is a section through 3 et of Fig. l. Fig. 7 is asection through l 2 of Fig. l.

The operatingleverB is fulcrumed at I) to the hollow standard A, whichis supported upon a base a, below which extends the discharge-pipe O,which communicates with the upper cylinder G below the piston E. Thispiston is hollow and has a hollow rod in two sections D and c, which arerepresented as connected by a link c at points d and c', respectively.These two sections, when thus connected, are operated together by thelever B, but may be disconnected, as will be eX- plained hereinafter.The section D is eX- tended to serve as an operating-rod, beingconnected to the end of lever B or other means forimparting to it areciprocating motion.

The lower piston-rod F F passes upward.. through the hollow upper pistonand rod, and is adjustably secured to the upper section D of the latterby means of a set-screw d'. The lower cylinder L is secured by boltsZbetween heads K and M, the suction-valve R forming the lower joint andhaving a weighted iiap o, and a suction-pipe extends downward from thehead M to any desired distance and terminates in a strainer N, as usual.

The casing connecting the upper and lower cylinders and inclosing thelower piston-rod is made up of sections united in such amanner as to beeasily disconnected or to permit a considerable variation in lengthwithout disconnecting. The extension H of cylinder G is of such diameteras to permit a section P of the casing to slip longitudinally within it,being secured by a set-screw h2, and packing 7L may be set up by agland-nut 7L to avoid leakage. The different sections of casing arecoupled together in a special manner to avoid the use of bolts and nutsand to facilitate the operation of coupling and unconpling. The ends ofadjoining sections are provided with rectangular heads having taperingopposite edges p, which are covered by corresponding cap-pieces p3,which are inclosed by a frame p4, having a set-screw p5, by means ofwhich the caps p3 are pressed together and the coupling effected. Thelower piston-rod is also made up of sections, which are coupled togetherin a special manner. Adjoining sections F F have hooked ends f f, whichenter an oblong sleeve f from opposite ends and engage radial holes inthe shell of said sleeve. A gib f2 fills up the sleeve and holds thehooked ends in place, while a cross-pin f3, of wood or equivalentmaterial, secures the gib to the sleeve. Coupling is easily effected andjust as easily parted, the wooden pin f3 serving to securely hold thegib in place during service, practically the whole strain coming uponthe hooked ends f, yet being easily cut by forcing the gib out of thesleeve to uncouple.

The lower pist-on consists of a shell \V, Figs. l and 2, provided with across-bar w', which IOO may be formed integral with the shell orseparate, a disk w2, having perforations w3, and a bucket w, formed froma Hat strip of leather or equivalent material, (see Fig. 4,) which, whenrolled and secured between the disk 'L02 and shell lV, assulnes inservice the shape shown in Fig. l. The rod F passes through the disk Q02and the cross-bar w', and the vzo leather w is clamped tightly in placeby means of nuts L05 and w on the threaded end of the rod, the formerserving also to hold in place a leather disk-valve 104, which closes theperforations in the disk 102 during the upward stroke of the piston.pose of this construction of piston is to avoid the necessity of aspecially-pressed leather bucket, the strip w being easily prepared byany one, and the ends being either butted or scarfed and lapped, so asto form a perfectlytight piston.

Under some circumstances as, for instance, when operated by a windmillitis preferable to have a sin gle-acting pump, thus avoiding alternatetension and compression upon the rod. When the link' c is attached.

to both section e and section l) of the upper piston-rod, as shown inFig. l, both pistons are moved together, thus operating as adoubleacting pump. To change to a singleacting it is only necessary todisconnect the link c at d and connect it to a fixed point a2, thuspreventing any movement of the upper piston, While the rod of the lowerpiston works freely through it. In order to Vary the length of the pumpWithin a comparatively short distance, it is `only necessary to slidethe casing and lower rod to the proper point and secure them by means ofthe set-screws h2 and d', or by other suitable means, and to set up thepacking h. When a considerable change A in length is required, one ormore sections of the casin g or rod can be readily added or removed bymeans of my improved couplings.

The main pur.

It is evident that the constructionherein set forth may be considerablymodified without departing from the spirit of my invention, and I do nottherefore limit myself precisely to said construction; but

WVhat I claim isy l. In a double-acting pump, the combination of upperand lower cylinders united by tubular sliding sections, substantiallyasdescribed, a hollow upper piston, a lower piston having a rod extendingthrough said hollow piston, a hollow operating-rod adj ustably securedto said lower piston-rod, and means, substantially as described, forconnecting said hollow piston With the lower piston-rod or with a fixedpoint, substantially as set forth.

2. In a pump, the casing-coupling herein described, consisting ofsimilar rectangular ends on adjacent sections with tapering oppositeedges p p', caps p3, and frame p4, with set-screw p5, substantially assetforth.

8. In a double-acting pump, the combination, with a lower piston androd, of a hollow upper piston and rod in tWo sections, the upper sectionbeing adjustably secured to said lower rod and the lower sectiondetachablv attached to said upper section, substantially as set forth.

4. In a pump, the piston-rod coupling herein described, consisting ofrods F, having adjacent hooked ends engaging corresponding holes in asleeve f', With gib f2 and pin f3,

y all substantially as set forth.

In testimon whereof I affix mv signature y u c in presence of twowitnesses.
